SAIL-FGROMMET.

SPECIFICATION forming part of Letters Patent No. 304,249, dated August 26, 1884.

Application filed June I, 1884. (h'o model.)

To alt whom it may concern:

Be it known that I, WILLIAM W. WrLcoX, a citizen of the United States, residing at Mid-' dletown, in the county of Middlesex and State of Connecticut, have invented new and useful Improvements in Sail-Grommets, of which the following is a specification.

This invention relates to a grommet which is made entirely of sheet metal, the cap-plate being formed on its outer edge with a olled rim and with spurs projecting from the inner edge of this rim, while the flange of the eyelet is also formed with a rolled rim, so that when the cap plate is brought down upon the cloth supported by the flange of the eyelet the spurs of said cap-plate will penetrate the cloth at such a distance from the edge of the hole in the cloth that they will take a firm hold, and that the grommet is not liable to come off. The rolled rimof the flange of the eyelet is slightly open, so that the points of the spurs of the cap-plate can turn down beneath said rim. On the inner edge of the cap-plate is also formed a rolled rim with spurs to give additional hold to the grommet.

In the accompanying drawings, Figure 1 represents a central section of my grommet before the eyelet is clinched, the cap .-plate being provided with spurs at its outer rim only. Fig. 2 is a similar section when the eyelet has been clinched. Fig. 3 is aside view of the cap-plate. Fig. 4 is a plan of the blank from which the made. Fig. 5 is a plan view of the blank used for forming a cap-plate with spurs at its inner rim as well as at its outer Fig. '6 is a section of the grommet-havthe plane of section berim. ing both sets of spurs, ing indicated by the linea; m, Fig. 5. a sectional made from the blank shown in Fig. 5. I

Similar letters indicatecorresponding parts.

In the drawings, the letter A designates the eyelet with its flange a. This flange is provided with a rolled rim, 6, which is slightly open, as shown in Figs. 1 and 2.

Bis the cap-plate, which is madeof sheet metal, and which, when provided with spurs at its outer rim only, is prepared from ablank such as shown in Fig. 4.. The outer edge of this cap-plate is provided with a-Jolled rim, 0, and from the inner edge of this rolled rim v Fig. 7 is detached sideview of the cap-plate distance to enable project spurs cl, and, if desired, the edge of the hole in the cap-plate may also be provided with spurs, as hereinafter explained. The eyelet is passed through a hole in the'cloth C, so that the cloth rests upon the rolled rimof the flange a. The cap-plate B is then applied, so that its spurs d will penetrate the cloth, as shown in Fig. 1, and when the eyelet is clinched the spurs are also clinched, as shown in Fig. 2. By referring to this figure it will be seen that the spurs d penetrate the cloth at a distance from the edge of the hole in the cloth, so that they are enabled to take a firm hold of the cloth, and in order to allow the spurs d to clinch, the rim b of the flange of the eyelet is left slightly open, so that the points of the spurs can turn under the inner edge of said rim.

In order to give to the grommet additional hold, the inner ed ge of the cap-plate B may be provided with a rolled rim, g, (see Figs. 6 and 7 and on this rolled rim are formed spurs h, which also penetrate the cloth, as shown in Fig. 6. The spurs h are, by preference, located on radial lines intersecting the spaces between the outer spurs, d, and they need not be quite so long assaid outer spurs. By form ing the spurs h on the inner edge of the rolled rim 9 these spurs are thrown off from the outer surface of the barrel of the eyelet a suffieient the same to take a firm hold in the cloth, as indicated in Fig. 6.. By these means a grommet is obtained which can be made comparatively cheap, properly applied to a sail, is not liable to come off I am aware that sail-grommets have heretoand which, when.

fore been made provided with points p'rojecting from the inner surface of the cap-plate or washer, and also from the inner surface of the flange of the eyelet, as described, for instance,

in Patent No. 5; 779, of September 19, 1848. In.

all cases known to me the parts composing the grommet were made of cast metal, which makes the article heavy, and, furthermore, the points, being situated close to the inner edge of the hole of the cloth, do not take a firm hold, neither do they readily clinch.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, inbefore described, with substantially as herethe eyelet A and its flangea, of a cap-plate, B, made of sheet metal, and provided with a roll ed rim, 0, and with spurs d, projecting from the inner edge of the rolled rim.

Y 5 2. The combination, substantially as hereinbefore described, with the eyelet A and its flange a, formed of sheet metal, and provided with an open rolled rim, b, of a cap-plate, B, made of sheet metal, and provided with a rolled [O rim, 0, and with spurs d, projecting from the rim, g, and spurs h, projecting from the inner j L edge of the rolled riin.

4. The combination, substantially as hereinbefore described, withthe eyelet A and its flange a, of a cap-plate, B, made of sheet metal, 20 and provided on its outer edge with :1 rolled rim, c,"and spurs (Z, and on its inner edge with I a rolled rim, y, and ,spnrs h.
